XRD studies of SiC and CeO2
XRD analyses were performed with a Philips APD 3720 powder
diffractometer using a Bragg–Brentano geometry with Cu Ka radiation
(k = 1.542 A) in the 2 theta-angle range from 10 to 70. Analyses
were performed on selected pellets described above as well as
samples specifically prepared for XRD analysis to study the interactions
of CeO2 with SiC.
